SPECIFICATION forming part of Letters Patent No. 307,703, dated Novembera, 1884.

Application filed August 4, 1883. (No model.)

To all whom it may concern.-

Be it known that I, H. CLAY Bnscorr, of Troy, in the county ofRensselaer, and in the State of New York,.have invented certain new anduseful Improvements in Stove Grates; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebcinghad to the accompanying drawings, making a part of thisspecification, in

which Figure 1 is a perspective View of my grate within thegrate-section or base of a stove, said grate being closed to shut offthe supply of air I to the fuel. Fig. 2 is a like view of the same 1partially opened. Fig. 3 is a perspective view of the parts of saidgrate separated from each other, and Figs. at and 5 are like views ofsaid grate in which are shown modifications in the construction of thesame.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to enable a supply of air to be readilyadmitted to or cut off from the outside of the fuel-chamber of a stoveand the same easily freed from ashes when desired; to which end saidinvention consists of the construction, arrangement, and combination ofparts, as hereinafter described, and more specifically pointed out inthe claims.

In the annexed drawings, A represents a circular grate which has at itsperiphery a flange, a, that extends upward and slightly outward for ashort distance and thence horizontally outward, as shown.

At the center of the grate A. is provided an opening, a, which ispreferably square, and is closed by means of a slide or valve, B, thatis capable of being moved so as to partially or entirely unclose saidopening. Said part B is preferably made to slide horizontally uponsuitable bearings, a and its operatingbar bis adapted for use inrotating said grate upon or around its axial center, as hereinaftershown.

At suitable points around its periphery the 4 grateA is provided withradial openings to", which are preferably formed partly within thevertical portion of the flange a and in part within the horizontalportion or body of said grate, and between said openings are preferablyprovided radial ribs a, that extend from or near the central opening, a,to the upper edge of said flange a, and serve not only to strengthensaid grate, but also to holdashes and to cause the same to be rotatedwith the latter when shaken.

The grate thus constructed rests within and is supported by an annularframe, 0, which has such form as to cause it to embrace the lower sideand periphery of the same, and at its center is provided with anopening, 0, that has a diameter somewhat less than that of a circlewhich would intersect the inner ends of the openings a. Said frame isalso provided with radial openings 0, that correspond in size, shape,and relative position to said openings a of said grate, so that by apartial rotation of the latter said openings a and 0 may be caused tocoincide, so as to permit of the passage of air, or each may be causedto come oppositeto the solid portion of said grate or frame, and thusout off the entrance of air.

The grate and frame thus constructed and combined is applied to a stovein the usual manner, and when arranged asshown in Fig. l prevents theadmission of air to the fuelchamber, but when arranged as seen in Fig. 2permits air to enter said fuel-chamber at the lower end around theoutside of the fuel, at which point the greatest good and best effect isproduced.

\Vhen the grate is closed, the ashes which rest upon the solid portionof the same fall over the openings a", and, resting upon theframebencath, effectually seal the same against the passage of air andenable the fuel-chamber to be effectually closed, so as to suspendcombustion of the fuel, while upon the opening of said grate said asheswill fall into the ash-pit and leave :li'rce passages for the air. 13ywithdrawing the slide 13 any ashes and cinders which have accumulatedupon the central portion of the grate will fall through the sameinto theash-pit.

\Vhile the central opening for the removal of ashes and cinders ispreferably employed, it may be omitted without affeeting'the operationof the other portions of said grate.

In Fig. 4: is shown a modification in the construction of the grate A,in which is omitted the portion of the flange a above the air-passagesc, while in Fi 5 said grate has circumferentially a corrugated form, andthe ends of the raised portions are adapted to close' said air-passagesc of the frame G, which passages ICU are formed wholly within thevertical portion of said frame.

I do not claim herein, broadly, as my invention a rotary fire-grateprovided with a series of openings near its periphery, and resting upona support also provided with openings with which those in the grate areadapted to come into coincidence as the grate is rotated, said grate andsupport being also pro vided with a central clumping-opening.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s- 1: A fire-grate adapted to be rotated around an axialcenter provided with a series of openings near its periphery and withradial ribs between such openings, in combination with the support uponwhich it rests and rotates, provided with a similar series of openingsadapted to be brought into and out of coincidence with the openings inthe grate by the rotation of the latter, substantiallyas shown anddescribed.

2. In combination with the grate-supporting plate provided with acentral opening and a series of openings near its periphery, the grateadapted to be rotated around its axial center, and provided with acentral opening closed by a suitable slide, and with a series ofopenings corresponding with those in the supporting-plate, and radialribs between these openings, and a handle by which the grate can berotated, and the slide moved to open and close the central opening inthe grate, substantially as shown and described.

3. In combination with the dish shaped grate provided with a series ofopenings in its bottom around the periphery thereof, and eX- tending upthe sides of the grate, the dishshaped support for the grate in and uponwhich the grate is adapted to rotate, and which is provided with aseries of openings similar to those in the grate into and out ofcoincidence with which the openings in the grate are brought as thegrate is rotated, substantially as shown and described.

4. A circular grate having a flat horizontal portion for supporting thefuel and an upright or standing portion around the edge thereof formedwith a series of lateral draft-openings, in combination with thecorrespondinglyshaped circular grate support within and upon which thegrate is adapted to be rotated to and fro, and which has in its uprightor Standing in the grate as the grate is rotated, substantially as andfor the purpose described;

In testimony that I claim the foregoing I have hereunto set my handthis23d day of l July, 1883.
